The Best Crib Mattresses of 2024
Here are 10 great crib mattresses to consider.
Newton Baby Crib Mattress

The mattress is also designed to regulate temperature. Regulating temperature reduces the potential for your baby to heat up at night, which can cause them to wake up when you really need them to sleep. It’s also Greenguard Gold certified and 100% recyclable.
At 11 pounds, this mattress is heavier than some others. However, it weighs less than most coil mattresses.
Pros
- 100% recyclable (eco-friendly).

This coil mattress has a waterproof vinyl cover to protect against spills and stains. But in many cases, waterproofing can mean added chemicals. This mattress, however, is Greenguard Gold certified, so you can rest assured your baby won’t be breathing in any hazardous chemicals while they sleep.

Personal Perspective
Bare and Back Are Best
The Centers for Disease Control (CDC) has done tons of work to promote safe sleeping habits for infants, also focusing on crib mattresses. As a result, infant deaths related to sleep have dropped dramatically since the 1990s (1).
While these practices don’t remove all risks, there are conscious choices you can make to protect your baby while they sleep. You can even use this helpful alliteration: Bare and back are best.
But what does it mean?
- Bare mattress: Your baby’s crib should have nothing in it except your baby, a tightly-fitted sheet, and the mattress. The CDC recommends removing blankets, toys, crib bumpers, and other items from the area. It might look lonely in there, but it’s the safest way for your baby to sleep.
- Back to bed: Babies should always sleep on their backs.
The CDC also recommends keeping your baby’s crib or bassinet in your room for at least six months (2). This lets you know quickly if something is wrong and minimizes the reaction time to address it. It’s also great for bonding and breastfeeding.
How to Choose a Crib Mattress
When you first begin searching for a crib mattress, the number of things to consider can seem endless. As is the case for many baby items, it’s important to be realistic about your family’s lifestyle. A mattress that works for someone else won’t always work for you.
Size
Different cribs call for different mattress sizes. If your crib mattress doesn’t fit properly, it can leave gaps on the sides that may endanger your child.
Luckily, crib sizes have been standardized by law since 2011 to ensure mattress and crib safety. Most crib packaging will state the crib size and recommend a mattress size that fits perfectly.
Check the Consumer Product Safety Commission (CPSC) website for periodic recalls and new standards (3).
Today, a standard, full-size crib has a width of approximately 28 inches and a length of around 52 inches (4).
A standard, non-full-size crib has a length greater than 55 inches or shorter than 49 inches, with a width greater than 30 inches or smaller than 25 inches (5). These cribs include foldable models and other variations.
Density and Resilience
If you’re like me, you love a mattress you can sink into. And, for adults, that may be fine. However, babies need something firmer.
Firm mattresses provide support for growing bodies and protect against suffocation. As your baby begins to roll over, softer mattresses can trap them on their stomach and make it more difficult to return to their back.
When you are at the store to buy your mattress, push down with your hands and watch what happens. Did the mattress conform to your hand? If so, it’s probably best to find something firmer.
Weight
I never once thought about the weight of my baby’s mattress until it was too late. After the pediatrician gave us the go-ahead to move her to her own bed in her own room, I asked my husband to get it ready for her.
When I changed her sheets for the first time, I was shocked. Changing sheets on a baby crib is essentially picking up dead weight from the worst possible angle. It’s not great for the back.
Mattress weights can vary greatly, and its material makeup will be a huge factor. I highly recommend picking it up in the store and pretending to change a sheet. New moms may look at you like you’re crazy, but veteran moms will get it.
Foam or Coil?
Mattresses can be made of many different materials. The material used can affect the mattress weight and cleaning protocol. Our crib mattress recommendations below include a variety of foam and coil mattresses, and both types have pros and cons.
Here are some general differences between foam and coil mattresses to help you decide which kind is best for you:
- Foam mattress: These are generally the lighter, cheaper option. They also offer more ventilation. They have a variety of firmness levels, so they’re not the same across the board.
- Coil mattress: These mattresses usually cost more and are heavier to lift. However, they’re likely to last longer and are more resilient to the potential damage that comes with babies and toddlers.
Organic, Eco-Friendly, or Conventional
Like many other retail goods, the crib mattress market has a growing organic and eco-friendly niche. Many brands will use the terms “natural” or “organic” for their mattresses, but it’s not as black and white as it seems.
Organic mattresses are made of materials that have reduced levels of chemicals, such as flame retardants. In 2017, the CPSC recommended manufacturers stop using organohalogen flame retardants in mattresses due to potential health effects (6).
Eco-friendly mattresses may be organic, or the manufacturer might just prioritize using a more sustainable supply chain. They may also use materials that make the mattress easier to break down after reaching the end of its useful life.
One Thing Is Certain
There are a variety of standards in use to help consumers verify products. These are a few of those standards:
- GOTS and GOLS: These standards certify that at least 95% of the mattress materials are certified organic. They also prohibit the use of chemical flame retardants (7) (8).
- Oeko-Tex Standard 100: Sets limits on emissions of formaldehyde and other chemicals.
- CertiPUR-US: Requires testing of certain chemicals, and prohibits the use of others, in foam mattresses.
New or Used
Do you have a mattress left over from your oldest child that you would like to reuse? Maybe your best friend has a child a few years older and wants to pass theirs down. Buying a brand new mattress for each child can seem wasteful, but are used mattresses safe?
It depends. Buying a used crib mattress from someone else, even your BFF, can be risky. You never know how it was cared for, and mattresses can easily mold if accidents and diaper leaks aren’t cleaned up properly.
If the mattress was yours, then you know if you took all the proper precautions in maintaining and storing it. If the mattress stayed somewhere dry, continues to meet current standards, and is not warped or worn, you can consider using it again.
Bottom Line
How to Clean Your Crib Mattress
Crib mattresses go through a lot. Babies have diaper blowouts, spit up, and get sick. All of these things mean liquids, germs, and other allergens are getting into your baby’s mattress.
Knowing this, it’s super important to keep your mattress clean. There are a couple of ways to do this, depending on how much gear you want to buy and your baby’s sensitivity to different materials.
Waterproof Mattress Pads
The easiest way to keep your mattress clean is to buy a waterproof mattress pad. Pads add an extra layer of protection between liquids and your mattress, and there are other benefits as well.
If you notice quite a bit of spit-up after a nighttime feeding, you can quickly take off the sheets and the mattress pad and throw them in the laundry. All you need to do is put on your replacement pad and a new pair of sheets, and your baby can be back to bed in less than 10 minutes.
Mattress pads, especially zippered pads, can also protect against bedbugs, mites, or other irritants. My baby was especially sensitive to dust, and changing to a zippered pad worked wonders. Many pads now come in cotton so they won’t make noise when your baby moves.
Detergents and Cleansers
If you would rather not buy a mattress pad, or the spill was so bad that it breached the pad, don’t worry. There are still options to keep the mattress clean.
For most spills, mixing a bit of baby-safe laundry detergent with water will do the trick. Make sure to soak up any liquid from the accident with a rag or paper towel before wiping clean. This will keep you from pushing liquids further into the mattress.
If you’re worried about bacteria, you can use rubbing alcohol on the spot after you wipe it clean with detergent. This will kill anything that’s still lingering from that naptime diaper blowout.
Keeping Dry
Ensuring your mattress is dry before putting it back in the crib is critical to avoid mold growth. For smaller spills, a few dabs with a dry paper towel after cleaning may be enough. For larger spills, you may want to find a sunny, well-ventilated area of your home to air dry it for a few hours.
Crib Mattresses FAQs
How Often Do You Need to Replace a Crib Mattress?
A crib mattress typically needs to be replaced if you can clearly see wear and tear, like sagging, tears, or stains that can’t be removed. A well-maintained mattress can last through multiple children, but it’s important to assess it for each child to ensure safety and comfort.
How Often Do You Flip a Crib Mattress?
Flipping a crib mattress every few months can help maintain its shape and prevent uneven wear. Some mattresses have a dual-sided design, featuring a side that’s more firm for infants and a softer side for toddlers, so be mindful of this when flipping.
What Is the Best Thickness for a Crib Mattress?
The best thickness for a crib mattress typically ranges between 4 to 6 inches. This ensures enough support for the baby while keeping the mattress fitting snugly in the crib, which is important for safety.
Is Memory Foam Good for Crib Mattress?
Memory foam is not typically recommended for crib mattresses, especially for infants, because it can create a surface that’s too soft. This poses a risk of suffocation and doesn’t provide the firm support infants need.
Do Breathable Crib Mattresses Prevent SIDS?
While breathable crib mattresses are marketed as safer, there’s no conclusive evidence that they prevent Sudden Infant Death Syndrome (SIDS).
The key to reducing the risk of SIDS is to follow safe sleep guidelines, like placing the baby on their back on a firm mattress with no loose bedding.
